This paper aims to classify a generalized coupled Lane–Emden system and to compute the
Noether operators corresponding to a Lagrangian for a generalized coupled Lane–Emden
system which occurs in the modelling of several ...

A number of photovoltaic pilot projects have been started in Botswana since 1990. The first photovoltaic project was Manyana PV project which started in 1992. The Japanese International Cooperation Agency (JICA) PV solar ...

We carry out the Lie group classification of the generalized Lane–Emden equation
xu00 þ nu0 þ xHðuÞ ¼ 0, which has many applications in mathematical physics and astrophysics.
We show that the equation admits a three-dimensional ...

Water scarcity in arid and semi-arid countries such as Botswana; call for judicious planning and economic use. In this connection many water saving components and appliances have been devised. One such system for example ...

Most studies consider business performance to be a multidimensional construct. Four
dimensions (namely, business growth, profitability, image and customer loyalty, and
product service innovativeness) were hypothesised ...

Cracking of the cover concrete due to steel corrosion is considered by many researchers to indicate the
end-of-service life of corrosion-affected reinforced concrete (RC) structures. Numerous models have been
developed ...

Botswana is facing one of its greatest development challenges at the moment. It is facing an HIV/AIDS pandemic of immense proportions. It is among the countries in the world that
have been hard hit by this scourge. A lot ...

Concrete is the widely used construction material worldwide. Therefore, for structural safety as well as to provide economic design, it is essential to understand well, its performance. Whilst in most developed countries ...

In order to analyse the strategic issues with regard to the South
African Platinum Group of Metals (PGM) industry, a risk analysis and an
assessment of the competitiveness of the industry were conducted. The analysis
of ...

The paper aims to compare predictions by different methods of analysis of the lateral load capacity of unreinforced masonry walls, and to determine whether a relationship can be drawn between theory and experiments. Several ...

Water reservoir storage requirements are a function of demand and variation in inflow. The greater the variation the greater the storage required to meet a specified draft. The selected recurrence interval of failure also ...

Three groups of methods for the inelastic analysis of steel plane frames with semi-rigid joints are considered in this paper. The first one
consists of simplified second-order (or P–Δ) plastic-hinge methods for the ...

Botswana’s mineral policy objective is primarily to maximize the national economic benefit from the development of mineral resources.
In 1999, the government replaced the old mining code of 1977, which was out of tune ...

The ensuing globalization of the construction industry as well as the highly fragmented and divisive nature of the industry are among the forces that are influencing it to seek management approaches such as strategic ...

The Project Management Section at the University of Botswana has been undergoing a test
to transform the section from an education based faculty to a research based faculty. The
test was initiated by a Fulbright Scholar ...

The lack of 'ubuntu'(African group solidarity) between project stakeholders in the Southern Africa Development Community (SADC) public building sector has been surrounded by controversy and strongly held opinions. The work ...
